I am 60 years old and have become this way also ... I used to have a normal sex life (have two children) and slowly lost desire to be with another sexually then slowly even lost interest in porn ... now find myself completely with no desire or even feeling ... as a test had my wife "handle" me last night with no reaction at all .. no sexual feeling ... bearly able to feel anything at all ... as a youngster wanted this because my sex drive was so high .. and partners were few and far between ... I guess the Karma caught with me ...lol
